    Thermodynamics problem help again

    Sorry for the second question in just a day, but my proffessor really didn't cover this material very well. Thanks for any help given :). A cylinder contains 4.22 mol of helium gas at a temperature of 314 K. The molar specific heat of helium at constant volume is 12.5 J/K mol. How much...

    How Do You Calculate Work Done by Gas in Thermodynamics?

    Thermodynamics problem: help needed! Gas in a container expands at a constant pressure of 95 atmospheres. Find the work done by the gas if the initial volume is 5 L and the final volume is 10 L. Answer in units of Joules. I thought this problem was straight-forward, but I missed it. I...

    Pressure and Net Force Question

    I'm working on my homework, and I have finished all the problems save for one. I think I am on the right track, but I'm lacking just a few bits of info. Here is the question (it has 2 parts, I have answered the first part correctly, but cannot get the second part correct). Part 1...

    Understanding kN in Torque Problems

    So if I had an answer like 1054.47 N, it would be 1.05447 kN?

    Understanding kN in Torque Problems

    Unit kN? What is it? I have a question asking for the tension in a cable that supports a beam. It asks me to find the answer in kN. What is kN? I know how to solve the problem, but I have no idea what this unit is...What is k? Figure at the bottom in an attachment. For the record...

    Torque and Tension of two weights

    Would that not leave me with the exact same initial equation that I started off with? I used that equation and came up with the wrong answer. Either I made a careless mistake (likely), I'm not understanding you, or there is something else wrong with the problem.

    Torque and Tension of two weights

    Guys - I'm back again :smile: . I hate to have so many questions, but I really appreaciate all the help you guys give me. For this problem, I am having some problems with the clockwise/counterclockwise Torque rule. Anyways, let me give you the problem and work. Two weights attached to a...

    Rotational speed versus linear motion problem

    Its an online homework thing that our professor uses. For our classwork, we actually have to use correct significant digits, but the homework agency doesn't "believe" in significant digits. Therefore, they assigned an arbitrary number...6...for all answers to come in. It makes things easier...

    Rotational speed versus linear motion problem

    The place I turn in the homework to always wants the answers in 6 significant digits...not the correct amount ;).

    Rotational speed versus linear motion problem

    Ah...No need to convert to radians then? I just remember my prof. hammering into us to work with radians :D. The changes this causes, for those who look at this problem later are as follows: theta = 0.47822 radians time = 0.0043492 seconds Velocity = 211.763 m/s

    Rotational speed versus linear motion problem

    Wow, all that work, and I just missed such a little thing. Thanks Integral ;). It oftentimes takes somone else to point out the careless mistakes. I really appreciate the help.
